■ Connecting a Computer

The following two methods are available for connecting the
DTXPRESS III to a computer.

1. Directly connect the computer’s serial port

to the DTXPRESS III’s TO HOST jack.

The method used for connect and transferring signals between a
computer and the DTXPRESS III is basically the same, no matter
what type of computer is used.
Use a cable to connect the devices and set the HOST SE-
LECT SWITCH according to the type of computer serial
port and clock used. Carefully read the instructions on
the right side of this page and select an appropriate cable
for the type of computer you are using.
The input signal from the TO HOST jack will be transmitted
to the DTXPRESS III’s tone generator and sequencer, and si-
multaneously transmitted to the DTXPRESS III’s MIDI OUT
jack. At this time, only message for the port number that is set
in the Utility mode’s [3-10. Host Thru Port] (Reference Guide
: P. 34) will be sent to the MIDI OUT jack. The signal from the
tone generator and sequencer is merged with the signal from
the MIDI IN jack and output to the TO HOST jack.

2. Connect the DTXPRESS III’s MIDI IN jack

to the computer through a MIDI interface.

• If you are using a computer equipped with a MIDI interface,
connect the MIDI OUT jack on the computer to the MIDI IN
jack on the DTXPRESS III. Set the HOST SELECT switch to
the “MIDI” position.
• If you are using a Macintosh series computer with an external
MIDI interface, connect the MIDI interface to the computers
RS-422 jack (modem or printer port), connect the MIDI OUT
jack on the interface to the MIDI IN jack on the DTXPRESS
III. Set the HOST SELECT switch to the “MIDI’ position.
* When the HOST SELECT switch is set to the “MIDI” position, the
transmission and reception via the TO HOST jack is ignored.

If you are using a computer equipped with a USB port, you
can connect the DTXPRESS III to your computer via a USB-
MIDI interface such as the YAMAHA UX16/96/256, etc.

Windows Users

Before you can exchange data between the DTXPRESS
III and your computer using the DTXPRESS III’s TO
HOST jack and your computer’s serial port connections,
you will need a suitable MIDI driver (Yamaha CBX Driver
(For Windows)) installed in your computer.
You can download the Yamaha CBX Driver from the XG
library at the Yamaha website given below.
